This ice bucket dump was about payback for Eli Manning

Eli Manning may be under plenty of pressure because of his slow transition to the West Coast offense, but at least the Giants' quarterback hasn't lost his sense of humor. An avowed practical joker, Manning's behind-the-scenes antics are apparently full steam ahead.

The latest evidence: After Tuesday's practice, center J.D. Walton took a bucket of ice water and dumped it over the head of an unsuspecting Manning. No, this wasn't a case of a teammate trying to shake up Manning with an impromptu ice shower. Nor was it pertaining to the Ice Bucket Challenge to raise awareness for ALS.

"That was just a little payback," Walton said after practice. "We'll just leave it at that. Just a little payback."

Walton didn't get into exactly what Manning had done to precipitate Tuesday's response. But he did have a few words for his quarterback after the dousing.

"I just told him, 'People don't forget,'" Walton said. "So I didn't forget when he had gotten me the first time."

Evidently, there will be more pranks ahead.

"I got a feeling that's about to happen," Walton said. "I might have woken up a monster."

Walton now hopes that fun starts to include a few more trips to the end zone. Manning's first-team offense has produced just two touchdowns in three preseason games, and head coach Tom Coughlin has implored his players to show significant improvement in Friday's exhibition against the Jets at MetLife Stadium.

"It's a process. Our goal is to put points on the board, and we haven't done that quite yet," said Walton, who suffered an ankle injury early in the 2012 season and missed the 2013 season because of complications with the injury. "Every day we come out here, that's our goal. We have a goal we want to score 'X' amount of points per game that we go out there, and we want our offense to be productive as much as possible. We're working every day to get towards that and to show it and put it on the field."

The chemistry on the offensive line is starting to get there, according to Walton.

"We have to work together every day, every play, every snap, where we have to be on the same page and we have to be thinking the same thing," he said. "There are a bunch of new faces up there on that line. We're working at it every day. We're working the kinks out and we're getting on that same page. This is a new offense for everybody, and we're pushing forward every day and getting better at things every day."
